Art Palmer, a 56-year-old physical trainer, says that four plain-clothes police stopped him after he purchased several Polo dress shirts and ties from Macy's store using his Macy's platinum card and American Express card, the Daily New reports. Palmer says that the police demanded that he show his receipt and the credit cards he used for the $320 transaction.

The officers told him that he was stopped four blocks away from the Macy's at Herald Square in New York because they lost him on the surveillance camera, Palmer told the Daily News.

He has filed a grievance with the Civilian Complaint Review Board, and the NYPD's Internal Affairs Bureau is also investigating the incident.
